The relatively seamless Metro service that began just before the holidays has continued into the new year.

There will be delays along the Red Line this weekend, as Metro continues its project to provide wireless service in all of its tunnel tracks. Red Line trains will run every 18 minutes, with an additional train every 8 minutes from Medical Center to Glenmont between 9 a.m. and 9 p.m. Otherwise, all other lines are running at normal intervals.
